"What is this sound I'm hearing....its beautiful?"
Usually said by an english speaking alien when it hears a piece of classical music.
Also, another thing that annoys me about some Predator fan fiction, is the idea of some ethnic person or villager from a 3rd world country describing the Pred as a "demon". I'm Indian and if I or any of my relatives ever come across something like a Pred we are gonna call it a mother f**king alien! Not "devil" nor will we have a back story or legend.
